STRAW-CUTTR.

SPECIFICATION forming part ot' Letters Patent No. 273,619, dated March6, 1883. Application tiled October 21, 1882. (No model.)

To all whom 'it may concern:

Beit known that I, JOHN N. SLAUGHEN- HAUP, a citizen of the UnitedStates, residing at Chambersburg, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements in Feedor Straw Gutters, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to an improvement in strawr or stalk cutters, andhas for its object the reducing of straw or stalksto suitable lengthsfor feeding stock and other purposes. I attain this object by means ofthe mechanism and construction hereinafter more fully pointed out in theclaims and specification.

Figure lis a perspective view of my iniproved stalk-cutter. Fig. 2 is alongitudinal sectional View of the same; and Fig. 3 is a ze detail view,showing the spring-plate and retaining-spring.

Asuitable feed-box, A, is formed and mounted at the outer end upon anuprightrpost or standard, withits opposite end inclined downward. Thistrough is formed to converge in the form of a spout at the inner end,which is supported upon a cross-bar, a. Beyond this trough, andregistering with it, is a deliveryspout attached to the outer frame andinclined 3o downward. Cross-bar a is attached at either end to uprightstandards B B, between which the spout end of the trough enters. At thef bottom 'of the spout, and on the inside, is secured a metalguard-strip, a', that prevents wearing ofthe wood, and also forms aguard for the knife.

Twoupright standards, B B, are formed with a cross-bar, b, at the bottomand a crossbar, c, about midway of their height, and on 4o the innerface ot' each standard is formed a longitudinal groove extending theirentire length. The purpose ot' this groove is to admit the tongue edgeof the gate C,which is formed of sufficient width to loosely passbetween the standards, and is also formed with a tongue on each edgethat loosely fits inside the grooves in the upright standards B B.

Ou its outer face, and near the center of gate O, is secured a pin, d,that is formed to pass 5o through a perforation in the hand-lever D,

| and the outer end of the hand-lever D is pivoted to a shortconnecting-bar, the opposite end ot' which is pivoted to the outer faceof one of the standards B. By means of this hand-lever D the gate O isforced up and down iu the guides between the uprights B B.

VOn the inner face ofthe gate C is diagonallyr secured a knife, e,beveled on its outer edge, and having a straight face on its inner side,so that the gate C in its downward movement 6o causes the inner face ofthe knife c to pass close to the metal guard-strip a.

Below the trough or feed-box A is pivoted a swinging press plate orgate, E, formed to swing inward and outward, and having secured acrossits upper end a thin metal strip,

f, the upper edge of which is in line with and presses against the upperedge of the guardpiece a. The inner upper corner of the metal stripf isslightly turned outward to allow the 7o descending knife to pass freelybetween the stripfand guard-piece a. The object of this metal plate andswinging gate is twofold: first, to clean the knife ot' any substancesthat may adhere to it; second, to form a rest or 73 lbearing for theoutside portions of the material being out, thus preventing' the outerends of the material from lopping down and crowding the knife, in itsdescent, away from the edge of the metal strip or guard a.

flo the inside of the swinging gate E, and near the center, isadjustably attached, by means of screw-bolt g, a spring, il, the outerend of which rests against the rear face ot' the standards B B, belowthe feed-trough. The purpose of this spring-bar It is to hold the metalstripf closely against the knife c in its vertical movement.

The operation of this device is obvious and needs no description. go

Having described my invention, what I desire to secure by Letters Patentis l. In a feed or straw cutter, a trough mounted on standards, asdescribed, the verticallysliding gute having a knife set diagonallyacross the inner facc of the same, the operating-lever connected to oneof said standards and by pivot-pin to the outer face of said slidinggate, and the press-plate pivoted ou a crossrod between said standardsand held against icc.

e y 273.619 f the descending knife by anfadjustable crossoutward, saidplate being adjustably held bar and screw-rod, each end of saidbar-rest'- against the knife e by spring-bar h, substanin g against therear face of said standards, tially as shown and specified.

substantially as shown and specified. In testimony whereof I affix my signature in 5 2. 1n a stalk or straw cutter, the combinapresence of twoWitnesses.
